// When an assignment expression position starts with an left parenthesis, the determination of the type
// of the syntax is to be deferred arbitrarily long until the end of the parentheses pair (plus a lookahead)
// or the first comma. This situation also defers the determination of all the expressions nested in the pair.
//
// There are three productions that can be parsed in a parentheses pair that needs to be determined
// after the outermost pair is closed. They are:
//
// 1. AssignmentExpression
// 2. BindingElements
// 3. AssignmentTargets
//
// In order to avoid exponential backtracking, we use two flags to denote if the production can be
// binding element or assignment target.
//
// The three productions have the relationship:
//
// BindingElements ⊆ AssignmentTargets ⊆ AssignmentExpression
//
// with a single exception that CoverInitializedName when used directly in an Expression, generates
// an early error. Therefore, we need the third state, firstCoverInitializedNameError, to track the
// first usage of CoverInitializedName and report it when we reached the end of the parentheses pair.
//
// isolateCoverGrammar function runs the given parser function with a new cover grammar context, and it does not
// effect the current flags. This means the production the parser parses is only used as an expression. Therefore
// the CoverInitializedName check is conducted.
//
// inheritCoverGrammar function runs the given parse function with a new cover grammar context, and it propagates
// the flags outside of the parser. This means the production the parser parses is used as a part of a potential
// pattern. The CoverInitializedName check is deferred.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* ##### Usage
*
* ```javascript
* // node.js, "classic" way:
* var MarkdownIt = require('markdown-it'),
* md = new MarkdownIt();
* var result = md.render('# markdown-it rulezz!');
*
* // node.js, the same, but with sugar:
* var md = require('markdown-it')();
* var result = md.render('# markdown-it rulezz!');
*
* // browser without AMD, added to "window" on script load
* // Note, there are no dash.
* var md = window.markdownit();
* var result = md.render('# markdown-it rulezz!');
* ```
*
* Single line rendering, without paragraph wrap:
*
* ```javascript
* var md = require('markdown-it')();
* var result = md.renderInline('__markdown-it__ rulezz!');
* ```
**/
/**
* new MarkdownIt([presetName, options])
* - presetName (String): optional, `commonmark` / `zero`
* - options (Object)
*
* Creates parser instanse with given config. Can be called without `new`.
*
* ##### presetName
*
* MarkdownIt provides named presets as a convenience to quickly
* enable/disable active syntax rules and options for common use cases.
*
* - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -
* configures parser to strict [CommonMark](http://commonmark.org/) mode.
* - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
* similar to GFM, used when no preset name given. Enables all available rules,
* but still without html, typographer & autolinker.
* - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -
* all rules disabled. Useful to quickly setup your config via `.enable()`.
* For example, when you need only `bold` and `italic` markup and nothing else.
*
* ##### options:
*
* - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
* That's not safe! You may need external sanitizer to protect output from XSS.
* It's better to extend features via plugins, instead of enabling HTML.
* - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
* (`<br />`). This is needed only for full CommonMark compatibility. In real
* world you will need HTML output.
* - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
* - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
* Can be useful for external highlighters.
* - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
* - __typographer__ - `false`. Set `true` to enable [some language-neutral
* replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +
* quotes beautification (smartquotes).
* - __quotes__ - `“”‘’`, string. Double + single quotes replacement pairs, when
* typographer enabled and smartquotes on. Set doubles to '«»' for Russian,
* '„“' for German.
* - __highlight__ - `null`. Highlighter function for fenced code blocks.
* Highlighter `function (str, lang)` should return escaped HTML. It can also
* return empty string if the source was not changed and should be escaped externaly.
*
* ##### Example
*
* ```javascript
* // commonmark mode
* var md = require('markdown-it')('commonmark');
*
* // default mode
* var md = require('markdown-it')();
*
* // enable everything
* var md = require('markdown-it')({
* html: true,
* linkify: true,
* typographer: true
* });
* ```
*
* ##### Syntax highlighting
*
* ```js
* var hljs = require('highlight.js') // https://highlightjs.org/
*
* var md = require('markdown-it')({
* highlight: function (str, lang) {
* if (lang && hljs.getLanguage(lang)) {
* try {
* return hljs.highlight(lang, str).value;
* } catch (__) {}
* }
*
* try {
* return hljs.highlightAuto(str).value;
* } catch (__) {}
*
* return ''; // use external default escaping
* }
* });
* ```

* - __value__ - rule to check tail after link prefix
* - _String_ - just alias to existing rule
* - _Object_
* - _validate_ - validator function (should return matched length on success),
* or `RegExp`.
* - _normalize_ - optional function to normalize text & url of matched result
* (for example, for @twitter mentions).
*
* `options`:
*
* - __fuzzyLink__ - recognige URL-s without `http(s):` prefix. Default `true`.
* - __fuzzyIP__ - allow IPs in fuzzy links above. Can conflict with some texts

// Changes from joyent/node:
//
// 1. No leading slash in paths,
// e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
//
// 2. Backslashes are not replaced with slashes,
// so `http:\\example.org\` is treated like a relative path
//
// 3. Trailing colon is treated like a part of the path,
// i.e. in `http://example.org:foo` pathname is `:foo`
//
// 4. Nothing is URL-encoded in the resulting object,
// (in joyent/node some chars in auth and paths are encoded)
//
// 5. `url.parse()` does not have `parseQueryString` argument
//
// 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
// which can be constructed using other parts of the url.

// synthetic stream cases, such as passthrough streams, _read
// may be a completely synchronous operation which may change
// the state of the read buffer, providing enough data when
// before there was *not* enough.
//
// So, the steps are:
// 1. Figure out what the state of things will be after we do
// a read from the buffer.
//
// 2. If that resulting state will trigger a _read, then call _read.
// Note that this may be asynchronous, or synchronous. Yes, it is
// deeply ugly to write APIs this way, but that still doesn't mean
// that the Readable class should behave improperly, as streams are
// designed to be sync/async agnostic.
// Take note if the _read call is sync or async (ie, if the read call
// has returned yet), so that we know whether or not it's safe to emit
// 'readable' etc.

hostHeaderName: optional header field name, used to override the default 'Host' header when used
behind a cache of a proxy. Apache2 changes the value of the 'Host' header while preserving
the original (which is what the module must verify) in the 'x-forwarded-host' header field.
Only used when passed a node Http.ServerRequest object.
nonceFunc: optional nonce validation function. The function signature is function(nonce, ts, callback)
where 'callback' must be called using the signature function(err).
timestampSkewSec: optional number of seconds of permitted clock skew for incoming timestamps. Defaults to 60 seconds.
Provides a +/- skew which means actual allowed window is double the number of seconds.
localtimeOffsetMsec: optional local clock time offset express in a number of milliseconds (positive or negative).
Defaults to 0.
payload: optional payload for validation. The client calculates the hash value and includes it via the 'hash'
header attribute. The server always ensures the value provided has been included in the request
MAC. When this option is provided, it validates the hash value itself. Validation is done by calculating
a hash value over the entire payload (assuming it has already be normalized to the same format and
encoding used by the client to calculate the hash on request). If the payload is not available at the time
of authentication, the authenticatePayload() method can be used by passing it the credentials and
attributes.hash returned in the authenticate callback.
host: optional host name override. Only used when passed a node request object.
port: optional port override. Only used when passed a node request object.

* Signed integer types, yay team! A reminder on how two's complement actually
* works. The first bit is the signed bit, i.e. tells us whether or not the
* number should be positive or negative. If the two's complement value is
* positive, then we're done, as it's equivalent to the unsigned representation.
*
* Now if the number is positive, you're pretty much done, you can just leverage
* the unsigned translations and return those. Unfortunately, negative numbers
* aren't quite that straightforward.
*
* At first glance, one might be inclined to use the traditional formula to
* translate binary numbers between the positive and negative values in two's
* complement. (Though it doesn't quite work for the most negative value)
* Mainly:
* - invert all the bits
* - add one to the result
*
* Of course, this doesn't quite work in Javascript. Take for example the value
* of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of
* course, Javascript will do the following:
*
* > ~0xff80
* -65409
*
* Whoh there, Javascript, that's not quite right. But wait, according to
* Javascript that's perfectly correct. When Javascript ends up seeing the
* constant 0xff80, it has no notion that it is actually a signed number. It
* assumes that we've input the unsigned value 0xff80. Thus, when it does the
* binary negation, it casts it into a signed value, (positive 0xff80). Then
* when you perform binary negation on that, it turns it into a negative number.
*
* Instead, we're going to have to use the following general formula, that works
* in a rather Javascript friendly way. I'm glad we don't support this kind of
* weird numbering scheme in the kernel.
*
* (BIT-MAX - (unsigned)val + 1) * -1
*
* The astute observer, may think that this doesn't make sense for 8-bit numbers
* (really it isn't necessary for them). However, when you get 16-bit numbers,
* you do. Let's go back to our prior example and see how this will look:
*
* (0xffff - 0xff80 + 1) * -1
* (0x007f + 1) * -1
* (0x0080) * -1
*
* Doing it this way ends up allowing us to treat it appropriately in
* Javascript. Sigh, that's really quite ugly for what should just be a few bit
* shifts, ~ and &.

* We now move onto IEEE 754: The traditional form for floating point numbers

* that someone is actually using this, as otherwise, this effort is probably

*
* One might be tempted to use parseFloat here, but that wouldn't work at all
* for several reasons. Mostly due to the way floats actually work, and
* parseFloat only actually works in base 10. I don't see base 10 anywhere near
* this file.
*
* In this case we'll implement the single and double precision versions. The
* quadruple precision, while probably useful, wouldn't really be accepted by
* Javascript, so let's not even waste our time.
*
* So let's review how this format looks like. A single precision value is 32
* bits and has three parts:
* - Sign bit
* - Exponent (Using bias notation)
* - Mantissa
*
* |s|eeeeeeee|mmmmmmmmmmmmmmmmmmmmmmmmm|
* 31| 30-23 | 22 - 0 |
*
* The exponent is stored in a biased input. The bias in this case 127.
* Therefore, our exponent is equal to the 8-bit value - 127.
*
* By default, a number is normalized in IEEE, that means that the mantissa has
* an implicit one that we don't see. So really the value stored is 1.m.
* However, if the exponent is all zeros, then instead we have to shift
* everything to the right one and there is no more implicit one.
*
* Special values:
* - Positive Infinity:
* Sign: 0
* Exponent: All 1s
* Mantissa: 0
* - Negative Infinity:
* Sign: 1
* Exponent: All 1s
* Mantissa: 0
* - NaN:
* Sign: *
* Exponent: All 1s
* Mantissa: non-zero
* - Zero:
* Sign: *
* Exponent: All 0s
* Mantissa: 0
*
* In the case of zero, the sign bit determines whether we get a positive or
* negative zero. However, since Javascript cannot determine the difference
* between the two: i.e. -0 == 0, we just always return 0.

* We now move onto our friends in the signed number category. Unlike unsigned

* arrays. Since we are only worrying about signed 32-bit values, we're in
* slightly better shape. Unfortunately, we really can't do our favorite binary
* & in this system. It really seems to do the wrong thing. For example:
*
* > -32 & 0xff
* 224
*
* What's happening above is really: 0xe0 & 0xff = 0xe0. However, the results of
* this aren't treated as a signed number. Ultimately a bad thing.
*
* What we're going to want to do is basically create the unsigned equivalent of
* our representation and pass that off to the wuint* functions. To do that
* we're going to do the following:
*
* - if the value is positive
* we can pass it directly off to the equivalent wuint
* - if the value is negative
* we do the following computation:
* mb + val + 1, where
* mb is the maximum unsigned value in that byte size
* val is the Javascript negative integer
*
*
* As a concrete value, take -128. In signed 16 bits this would be 0xff80. If
* you do out the computations:
*
* 0xffff - 128 + 1
* 0xffff - 127
* 0xff80
*
* You can then encode this value as the signed version. This is really rather
* hacky, but it should work and get the job done which is our goal here.
*
* Thus the overall flow is:
* - Truncate the floating point part of the number
* - We don't have to take the modulus, because the unsigned versions will
* take care of that for us. And we don't have to worry about that
* potentially causing bad things to happen because of sign extension
* - Pass it off to the appropriate unsigned version, potentially modifying
* the negative portions as necessary.

* Now we are moving onto the weirder of these, the float and double. For this

* have no way to get at the underlying float representation, at least not
* easily. But that doesn't mean we can't figure it out, we just have to use our
* heads.
*
* One might propose to use Number.toString(2). Of course, this is not really
* that good, because the ECMAScript 262 v3 Standard says the following Section
* 15.7.4.2-Number.prototype.toString (radix):
*
* If radix is an integer from 2 to 36, but not 10, the result is a string, the
* choice of which is implementation-dependent.
*
* Well that doesn't really help us one bit now does it? We could use the
* standard base 10 version of the string, but that's just going to create more
* errors as we end up trying to convert it back to a binary value. So, really
* this just means we have to be non-lazy and parse the structure intelligently.
*
* First off, we can do the basic checks: NaN, positive and negative infinity.
*
* Now that those are done we can work backwards to generate the mantissa and
* exponent.
*
* The first thing we need to do is determine the sign bit, easy to do, check
* whether the value is less than 0. And convert the number to its absolute
* value representation. Next, we need to determine if the value is less than
* one or greater than or equal to one and from there determine what power was
* used to get there. What follows is now specific to floats, though the general
* ideas behind this will hold for doubles as well, but the exact numbers
* involved will change.
*
* Once we have that power we can determine the exponent and the mantissa. Call
* the value that has the number of bits to reach the power ebits. In the
* general case they have the following values:
*
* exponent 127 + ebits
* mantissa value * 2^(23 - ebits) & 0x7fffff
*
* In the case where the value of ebits is <= -127 we are now in the case where
* we no longer have normalized numbers. In this case the values take on the
* following values:
*
* exponent 0
* mantissa value * 2^149 & 0x7fffff
*
* Once we have the values for the sign, mantissa, and exponent. We reconstruct
* the four bytes as follows:
*
* byte0 sign bit and seven most significant bits from the exp
* sign << 7 | (exponent & 0xfe) >>> 1
*
* byte1 lsb from the exponent and 7 top bits from the mantissa
* (exponent & 0x01) << 7 | (mantissa & 0x7f0000) >>> 16
*
* byte2 bits 8-15 (zero indexing) from mantissa
* mantissa & 0xff00 >> 8
*
* byte3 bits 0-7 from mantissa
* mantissa & 0xff
*
* Once we have this we have to assign them into the buffer in proper endian
* order.

* Now we move onto doubles. Doubles are similar to floats in pretty much all

*
* We're going to proceed in an identical fashion to floats and utilize the same
* helper functions. All that really is changing are the specific values that we
* use to do the calculations. Thus, to review we have to do the following.
*
* First get the sign bit and convert the value to its absolute value
* representation. Next, we determine the number of bits that we used to get to
* the value, branching whether the value is greater than or less than 1. Once
* we have that value which we will again call ebits, we have to do the
* following in the general case:
*
* exponent 1023 + ebits
* mantissa [value * 2^(52 - ebits)] % 2^52
*
* In the case where the value of ebits <= -1023 we no longer use normalized
* numbers, thus like with floats we have to do slightly different processing:
*
* exponent 0
* mantissa [value * 2^1074] % 2^52
*
* Once we have determined the sign, exponent and mantissa we can construct the
* bytes as follows:
*
* byte0 sign bit and seven most significant bits form the exp
* sign << 7 | (exponent & 0x7f0) >>> 4
*
* byte1 Remaining 4 bits from the exponent and the four most
* significant bits from the mantissa 48-51
* (exponent & 0x00f) << 4 | mantissa >>> 48
*
* byte2 Bits 40-47 from the mantissa
* (mantissa >>> 40) & 0xff
*
* byte3 Bits 32-39 from the mantissa
* (mantissa >>> 32) & 0xff
*
* byte4 Bits 24-31 from the mantissa
* (mantissa >>> 24) & 0xff
*
* byte5 Bits 16-23 from the Mantissa
* (mantissa >>> 16) & 0xff
*
* byte6 Bits 8-15 from the mantissa
* (mantissa >>> 8) & 0xff
*
* byte7 Bits 0-7 from the mantissa
* mantissa & 0xff
*
* Now we can't quite do the right shifting that we want in bytes 1 - 3, because
* we'll have extended too far and we'll lose those values when we try and do
* the shift. Instead we have to use an alternate approach. To try and stay out
* of floating point, what we'll do is say that mantissa -= bytes[4-7] and then
* divide by 2^32. Once we've done that we can use binary arithmetic. Oof,
* that's ugly, but it seems to avoid using floating point (just based on how v8
* seems to be optimizing for base 2 arithmetic).

* ctype.js
*
* This module provides a simple abstraction towards reading and writing
* different types of binary data. It is designed to use ctio.js and provide a
* richer and more expressive API on top of it.
*
* By default we support the following as built in basic types:
* int8_t
* int16_t
* int32_t
* uint8_t
* uint16_t
* uint32_t
* uint64_t
* float
* double
* char
* char[]
*
* Each type is returned as a Number, with the exception of char and char[]
* which are returned as Node Buffers. A char is considered a uint8_t.
*
* Requests to read and write data are specified as an array of JSON objects.
* This is also the same way that one declares structs. Even if just a single
* value is requested, it must be done as a struct. The array order determines
* the order that we try and read values. Each entry has the following format
* with values marked with a * being optional.
*
* { key: { type: /type/, value*: /value/, offset*: /offset/ }
*
* If offset is defined, we lseek(offset, SEEK_SET) before reading the next
* value. Value is defined when we're writing out data, otherwise it's ignored.
*
